Shandong Darby tunnel fire retardant paint

SH (SD-17) tunnel fire retardant coating is a new product developed by our company. Set insulation, fireproofing dual functions in one. Mainly used in industrial and civil buildings and roads, railways (including subway) tunnels and other concrete surface, can form a protective layer fire-resistant insulation case of fire, in order to improve its fire-resistant structures. The product is non-toxic and tasteless, safety and environmental protection. Performance (Executive GA98-2005 "concrete structure fire retardant coating") No. Item Specification Technical Inspection Results 1 state in the container after stirring was thick liquid, non-caking meet the requirements of 2 Drying time (Table dry) / h ≤24 163 bond strength / MPa ≥0.1 0.2 4 dry density / kg / m3 ≤800 620 5 after water resistance test after 720h, the coating does not crack, from the floor, shedding, allowing a slight discoloration of hair up and meet the requirements 6 Acid by After 360h test, the coating does not crack, from the floor, shedding, allowing a slight discoloration of hair up and in line with the requirements of 7 after the alkali resistance test after 360h, the coating does not crack, from the floor, shedding, allowing a slight discoloration of hair up and meet the requirements of 8 resistance to thermal cycling resistance / time after 15 tests, the coating does not crack, from the floor, shedding 9 meet the requirements of resistance to heat discoloration warp 720h test, the coating does not crack, layer, loss, discoloration meet the requirements of 10 fire-resistant performance coating thickness / mm 20 + 2mm 12 21 FIRE RESISTANCE / h 2.0 2.0 3.0 Construction Technology: 1, pre-construction deal with the concrete surface dust, decontamination. The concrete surface is too smooth, then its surface nap and other measures taken to deal with. 2, (1) the ratio of coating paint: water = 1: 1-1.2 (2) paint mixing paint with water in a blender and stirred for 5-8 minutes to use, mixing good material to be used within 1h. (3) construction methods mechanical spraying by hand trowel or trowel 3, the thickness of the first pass of construction to be used by spraying construction, after construction of each pass freely selectable spray or trowel. 4, the first pass thickness of not> 3mm, until completely dry process can be carried out at times, after each pass coating thickness of not> 8mm, the interval should ≥24h. 5, the construction temperature requirements above 0 ℃. Notes: 1. The coating at room temperature in the storage, shelf life of six months. 2, the product is non-flammable, non-explosive, non-toxic, non-corrosive products storage and transportation security only pay attention sealed to prevent moisture and rain water ingress, damp material that is invalid
